IMPROVEMENT IN HAY-RAKERS AND. LOADERS.

'IO ALL WHOM IT MAY CONCERN:

Be it known that I, OItrJN LUCE, of Virgil, in the county of Oortland, and State of New York, have invented anew and improved Hay-Baker and Loader; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a side elevation.

Figure 2 is a longitudinal vertical section. n

Figure 8 is a vertical section of the wheels and axles, through the line :r :v of iig. -l.

In this invention an improved adjustable device is employed for clearing the teeth and conveying the hay to the elevator, and in connection with it other novel devices are employed for raising and lowering the teeth and the clearing-apparatus. l

In the drawings, A represents the frame of mymachine, and a is a hook for coupling it to'the wagon in which the hay is to be loaded; B B are the draught-wheels running on a hollow hub, H', C, the carrier or elevator; O C', guide-rods toikeep the hay on the carrier, and D D the rake-teeth, supported by a rockingshaft, 0l, which can be rocked, so as to raise or lower the teeth by means of a lever, d. E is a gauge, by which said lever can be fixed at any desired inclination, and e is a spring which allows the rake-teeth to rise and pass over inequalities in the ground without breaking. Just inside ot' each draught-wheel is a rag-wheel, F, running on a hollow hub, H, in the same manner as the draught-wheels, and carrying one of the endless chains Gr G of the elevator. Straight bars I I I connect the rims of the two rag-wheels, forming a kind of open hollow cylinder, extending across the machine between the rag-wheels, and revolving with them. Within this revolving cylinder is a fixed bar, J, extending the whole length oi` the cylinder, and supported eccentrically as to it by means hereafter to be described.

This bar furnishes a bearing for several rotating arms 1n m m, one end of each of which is bent into a loop around the bar, the other end projecting loosely through a hole, t', in the bars I I I that compose the rim ofthe cylinder. The bar J being fixed and out of centre with the revolving cylinder, the arms m m m will project through the holes L'tto a diil'erent degree on each side of the cylinder, extending farthest beyond the rim of the cylinder on the side nearest to which the bar J is stationed, and assuming the position shown in g. 2. As the rag-wheels revolve, the arms nt m m will be caused to rotate, and, projecting considerably through the wall of the rotating cylinder on its under and rear sides, will pick up the hay, force it round against the teeth D D,

and carry it up over the cylinder to the endless elevator C, upon which they will drop it, and retire within the cylinder by reason of their 'own eccentricity with the latter. W'hcn the cylinder moves round so far that the arms again assume a nearly vertical position, theywill emerge from their holes7 and again act upon the hay as before. One arm, m, will be arranged tooperate between each pair of' adjacent teeth D D.

It is evident from the above that the bar J mus't be supported inside ofthe cylinder, so that the latter can revolve around it. In order to eiiect this, I make the hubs H H' of the draught-ivl1cels and rag-wheels hollow, as shown in fig. 3, and support the bar J on the end of an arm or crank, l?, attached to a'cylindrical axle-shaft or spindle, R, that extends through the hollow hubs. The draught-wheel, rag-wheel, and cylinder can then revolve without imparting a rotating motion to the bar J. This also enables me to render the position of the bar J adjustable, which I accomplish by simply attaching a short lever, L, to the outer end of the axle or spins dle R. As the handle of this lever is depressedor raised, the position ofthe bar J is correspondingly elevated or lowered'. o o o o are a series of holes by which, in connection with a pin, p, the lever L may be held in any required position. By depressing the lever and pinning it to the lower hole o, the bar J will be thrown up so far that the arms 'm m m will not come near the ground in their revolutions-a thing which may be very desire ble when driving to or from the field, or over rough ground. At the same time the rake-teeth D D may, by the lever d', be thrown up out ofthe way, as shown in red lines in iig. 1.

The bar J, crank P, and spindle It, when cast in oneA piece, may form the axle-tree, the rag-wheel F and wheel B running separately upon it, as shown in tig. 3, and being connected by a'clutch, or ratchet and pawl,

which allows the wheel B to back without moving the rag-wheel, but when it moves forwnrcl communicnfes its motion to the rag-wheel and elevator. The axle o1" shaft R is prevented from turning withthe wheel by means of u bolt, which passes through it and through the lever L; I' c c e ure-rollers upon which the chains G G :ire carried.

v Having thusv describod my invention, what I'claim as new, unil desire to secure by Letters Patent, is=

1. The eccentric-bar J, when supported as described, nud operating in connection with the arms m m m, the revolving bars I Il, and the teeth D D, substantially as an 1 for the purposes set forth.

2. The combination of the independent lever d with the rocking-shaft d, teeth D D, gauge E, and spring e, substantially as and for the purposes indiatod. u v
